Kim Kardashian is said to be horrified after a second sex tape starring her has gone on sale for £19 million.

The X-rated footage allegedly features the 32-year-old reality TV star and her ex-boyfriend Ray J engaged in erotic acts which are even raunchier than their first home video which leaked in 2007 and eventually released as a DVD entitled 'Kim Kardashian: Superstar'.

A source told the Daily Star newspaper: ''It's definitely Kim in the video. And it's even raunchier than her last one. There are all kinds of eye-popping moments.''

Kim is said to be terrified the latest sex tape will appear online and cause problems in her relationship with 35-year-old rapper Kanye West.

The source added: ''Kim fears this will damage her relationship with Kanye West.''

The TV beauty narrowly avoided an embarrassing encounter with R&B singer Ray J, 31, last month when she sneaked out of Prime 112 restaurant in Miami to ensure she missed him.

A source explained: ''Kim and Kris Jenner posed for pictures in front of the restaurant to allow Kourtney and son Mason to sneak out the side entrance unnoticed.

''And just by a few moments, Kim missed Ray J, who was seen entering the restaurant to meet a large group of friends including boxer floyd mayweather.''

Kanye was involved in his own sex tape scandal in September when a 20-minute recording surfaced featuring him and a girl who looks just like Kim.
